Multisig and paper wallet

Use a QR code generator to create QR codes of the public keys, and then print those codes on paper. This will save you from having to write out the long strings of characters by hand, and also reduces the risk of mistyping.

It introduces another risk: QR-code generators and readers often contain malware (such as replacing Bitcoin addresses by another one), and you don't want to use an online phone to scan a paper wallet. Clear text is much safer, just take a few minutes to type accurately.

My point was one does not need to keep the Master Public key saved as they can find the keys when they try all three seeds one by one and each time they will get each Master Key. Then combine the master key and seed to recover the wallet. For a 2 of 3 wallet, two set is enough.

Half the point of a multi-sig is to have redundancy in the set up. A 2-of-3 wallet allows you to lose one seed phrase and still be able to recover your wallet, provided you have all three master public keys. If you don't save the master public keys, then you need all three seed phrases in order to recover the wallet, even if the wallet itself is 2-of-3.

You should absolutely back up your master public keys alongside your seed phrases. Without a copy of your master public keys, then you need to recover every single one of your seed phrases, which defeats the point of having a threshold number of signers.

I agree with the part of redundancy. But a multisig wallet is better than a standard wallet in terms of security. In the cases of compromised wallet information a hacker or bad actor at least needs to access more than one device to steal the funds.

If anyone as me how to keep their coins securely? My first suggestion is to buy a hardware wallet. And the second suggestion is to set up a m of n multi sig wallet.

In the cases of compromised wallet information a hacker or bad actor at least needs to access more than one device to steal the funds.

But this is only true if you have backed up your master public keys as you should have done. If you only have seed phrases, then to recover your wallet you must import all those seed phrases in to the same device, which completely removes the benefit of a multi-sig wallet requiring the compromise of multiple devices.
